Danaus plexippus (The Monarch)

Danaus plexippus (The Monarch)

This week our shipment comes to us from Costa Rica, and among various species of butterflies we will also receive a handful of Monarchs, Danaus plexippus.

People really love this species and we rarely get it. The Monarchs in the U.S., Canada and Mexico are part of large-scale, long distance migrations that typically happen from August to October. They can cover thousands of miles and survive by stopping to feed on nectar and roosting together at night. There are populations of this species in many parts of the world with different behaviors and different migration habits. Those in Costa Rica have a migration from the East to West Coasts.

Of course, the Monarchs that we get from Costa Rica have all been farm-raised. None are taken from the wild.

Come visit our Tropical Butterfly House and take a look at our Monarchs migrating from flower to flower. Bring your camera to snap a shot of their unique coloring.

“Fresh Sheet” is our weekly shipment report of pupae on display in the emerging window. Visit Pacific Science Center’s Tropical Butterfly House and meet our newest residents.These butterflies typically arrive as pupae on the Thursday or Friday before the Fresh Sheet is published. Some of these butterflies will start emerging the day they arrive or the next day, but other species may take a full week before they reach adulthood. After emerging, they may live for a week or even a few months! While we love sharing a variety of species with our guests, we cannot guarantee that any specific species will be flying on the day that you visit Pacific Science Center.If you are interested in photographing a specific butterfly and would like to be updated about when it is flying in the Tropical Butterfly House, please email with details and your contact information.
